Review Loupe 4.0 Notes

Since this is an update release you should read Getting Started - What's New - Version 4.0 for a more complete picture of the new capabilities in 4.0.

Upgrading Loupe Server

For details on how to upgrade your on-premises Loupe Server installation see Loupe Server Administration - Upgrading to a New Version.

New Features in This Release

Azure Blob Storage for Server

Loupe Server can now use Azure Blob Storage for storing session files.  This provides a lower cost, more reliable, and higher performance solution for large file storage.  For this version this feature is only available with Enterprise Edition but will be expanded to Standard Edition in a future release.

Application Version Drill-in Navigation Improvement

Drilling into a single application version from a general dashboard or another circumstance where the web UI is not already focused on a single application will switch to the related application and select the Application menu from the top-level navigation.  This facilitates moving laterally to other application versions within the same application.

Live Session Extensions

Loupe Extensions that define session commands now apply to live sessions as well as repository sessions.  These can be distinguished by the IsLive property which was added to the ISessionSummary interface.

Show Milliseconds Option for Session Viewer is Persisted

When selecting Show Milliseconds in the session viewer the setting is applied to all the various session views (including log messages, metric grids, and metric chart details).  This setting is persisted when the session viewer is closed and applied the next time a session is viewed.

Compatibility

Loupe 4.0 is generally backwards compatible with 3.0 with the following notes:

• Agent: Requires Server version 4.0 and Desktop 4.0 due to new data types introduced in this version.
• Server: Fully backwards compatible with older Agents. Older Loupe Desktop clients will not be able to use AddIns.
• Desktop: Compatible with Server versions 3.7.0 and later.  Compatible with any version of Agent.
• Extensions must be modified:  Any Loupe Addin developed for an Loupe 3.* will need to be updated to use the new Loupe Extension types and repackaged.  Confirmation information has been moved so each extension will need to be reconfigured once it is installed.  See Loupe Extensions - Getting Started for more information.

Defects Fixed In This Release

Agent

• Fixed: MaxLocalDiskSize and MaxLocalFileAge can't be set to a value less than one in a configuration file, preventing disabling these limits with file-based configuration.

Desktop

• Fixed: Significant memory leak when connected to a server repository with Live Sessions enabled. (Defect introduced in 4.0.1)

Server

• Fixed: Server Administrator is unable to add, edit, or remove a mailbox to monitor.
• Fixed: Server Administrator displays an exception if the user deletes a storage server with storage volumes.
• Fixed: Server Administrator can't work with extensions compiled against Loupe Extensibility 4.0.0.0.
• Fixed: Connection instructions displayed in the web dashboard can contain invalid XML formatting.
• Fixed: Label for Release Type is misleading in Issue Rules.
• Fixed: Main web dashboard displays outdated information initially for at least five seconds.
• Fixed: Product Application Mapping rules save empty strings instead of nulls for values that are not being modified, preventing rules from functioning.
• Fixed: Adding redaction rule from an event creates an invalid rule due to HTML Escaping of characters for certain special characters like quote.
